Hubble 25th Anniversary Series – The Incredible Time Machine

With about a million observations under its belt during its 25 years of service, some of the Hubble Space Telescope's most memorable images have been of the vastness of space and the early days of the universe. These "deep-field" images actually improved over the years because shuttle astronauts were able to upgrade the observatory. This episode, entitled "The Incredible Time Machine" shows us how Hubble has been able to give us a glimpse of a cosmos in its formative years.
